This is my first post here. I just upgraded (well, reinstalled) to Ubuntu 15.10. I'm using the closed source nvidia driver with 2 video cards and 4 monitors (2 per card).

I'm Using X-screen0 for the 'normal' unity/compiz desktop and I'm running vmware in full-screen mode on X-screen1 with openbox as a window manager.

The problem is on X-screen0, running unity/compiz. Whenever I maximize a windows on my left monitor, the window will get maximized on the right monitor. A second, maybe unrelated, issue is when some window is active, and I click within a browser on the left monitor, that window will move to the right, slightly into my right monitor.

When I disable my 2 monitors on X-screen1 i can get things to work only when I set my right monitor as primary in nvidia-settings, otherwise windows will maximize spanning both monitors.

This is my xorg.conf: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 352.21 (buildd@lgw01-37) Thu Jul 23 11:50:49 UTC 2015

I've tried using the 'put' compiz plugin, and using a "put to adjacent viewport" shortcut, but this has no effect (i.e. pressing the shortcut does nothing).

I'd like to watch some youtube crap on my left monitor while working on the others :)

Let me know if you need more info about my setup.

Okay, apparently my problem has been magically solved.

I apt-get'ted plasma-desktop and tried that, just to see if that would allow me to maximize windows on both monitors. Nope. I could not even drag windows to my left monitor. It would split-screen maximize the window on the right monitor instead. Not feeling like fiddling with an unfamiliar desktop environment for too long, I purged it. After which, back in my unity desktop, things magically worked! I can maximize windows on both monitors. Watch videos full screen on either monitor and the strange moving/jumping of a window when giving it focus on my left monitor has disappeared as well.

I have no clue why things are working now, but they are. :)
